Henry Moran's second hand

If Henry is unbooted when you would reveal an illegal draw hand during lowball, boot Henry, discard the illegal hand, and reveal the top five cards of your deck as your hand instead.

I have been told that after revealing the top five cards when triggering Henry’s ability, you put them back on top of your deck and do not discard them, since the card only states to “reveal” and not “draw”. Is that the case?

Hello! The initial hand is discarded per Henry’s text:

If Henry is unbooted when you would reveal an illegal draw hand during lowball, boot Henry, discard the illegal hand, and reveal the top five cards of your deck as your hand instead.

The second hand is discarded because it becomes your new hand and procedure for lowball continues as normal with the hand going to discard.
